IMPROVEMENT IN HARRQWS.

The Schedule referred to these Letters lPatent and mln'ng pari of the same.

To all Iwhom it may concern,

Be it known that I, GEORGE PADDINGTON, of Springville, in the county 'of Linn, and State of Iowa, have .invented a new and improved Harrow; and I do hereby declare thatthe following is a full, clear, and exact description thereof, which will 'enable others skilled in theait to makand use the saine, reference lying. drawings, forming part of this specification.

In the accompanying sheet of drawings- Figure 1 is a side sectional view of my invention, taken in the line' a: x, iig. 2.

- Figure 2 is a plan or top view ofthe. same.

Figure 3, a-vertical section of a vportion of the harrow, taken in the line y y, fig. 2. t

Similar letters Aof reference indicate corresponding parts. l A represents a rectangular frame, which is mounted on 'two wheels,B B, the latter being keyed on an axle,

C, which turns with the wheels.

D is the dranghtpole,attached to the front part of the flame A, and

.E, the drivels seat, placed on the rear part thereof.

The harrow is composed of two parts, F F', each part being of V-form, and placed one within the other, as shown clearly in tig. 2. y l

The front ends of the oblique sides a. c' of each part of the barrow are connected by a vertical hinge, b, and the rear ends of said sides are connected by extension-bars G, arranged in any` proper way. y

The parts F F are connected at their front ends by means of a coupling-link, o.

1 By this means, the two parts oi' the barrow may be expanded or contracted, as desired; 4 'lhc rear-ends of the parts F h" of the harrow are suspended from the'frame A by plates o,-`and"the front end of the outer part F is suspended frodi-,the frame or rear part ofthe draught-pole by a link, da,

H represents the tee l1 of the harrow, which are composed each vof a tube, e, having a flange, f, at'it's upper' end. These anges of the tubes rest on the edges of the plates g around the holes, (see fig. 3,) through which the tubes pass, said plates being attached to the side-pieces a of. the barrow, and through said side-pieces'pins h pass into the tubes e,said pins serving to steady the tubes and retain them' firmly in position. l

The tubes e, by this arrangement, are allowed to revolve or turn freely, and consequently will not bey liable to choke or clog up, as is the case with the ordinary rigid or fixedvteeth. I ,a

The side-pieces w a are divided or composed each of two or more parts, connected by hinges d, which admit of the side-pieces being raised whenever required in order to pass over obstructions. v

Having thus described my invent-ion,

,l What I claim as new, and desire to secure ters Patent, is t A barrow-tooth, formed of the tube e, revolving about a central pin, 7i, as shown and described,
